In "Week 3” (Which actually takes place as Week 1), the corruption faces Pico, who is already halfway corrupted during the first song. Due to the nature of the Corruption only spreading through sound and physical contact, it is possible Pico had attempted to physically fight Boyfriend, or some other corrupted being, before what happens on screen. In the first 2 songs Boyfriend is looking directly at the player. In the second song, the most notable occurrence is Boyfriend (part of his face and body) & Pico (a fraction of his body) having been partially uncorrupted. Boyfriend was likely uncorrupted due to having known Pico very well. The connection may have been effective against this corruption. However, Boyfriend was wearing his Christmas clothing when he was corrupted, so it is possible Boyfriend was not actually uncorrupted at all, and the Corruption was simply trying to trick Pico into lowering his guard.
